About Tesseract Investment

Tesseract is a leading digital asset yield generation platform, trusted by institutional and retail partners worldwide. We help exchanges, custodians, and fintechs offer best-in-class crypto yield products while maintaining the highest standards of security and transparency. Backed by a robust technology team and experienced leadership, Tesseract has scaled rapidly, becoming one of the most credible players in the yield-bearing ecosystem.

We are now entering our next growth phase—expanding our Earn API offering and improving product ownership to deliver a world-class experience to our partners.

The Role

We are seeking a dynamic and hands-on Product Manager to take full ownership of our Earn API product, the integration that powers partner exchanges and platforms to offer yield products to their end customers.
This is a critical role for Tesseract, directly impacting revenue growth and client satisfaction. The right candidate will manage the product end-to-end: from defining the roadmap and improving integrations to shaping the client journey and ensuring seamless delivery with engineering.
For the right person, this role offers a path to Head of Product within 18 months.

What You’ll Do

Own the Earn API product lifecycle end-to-end – from strategy to execution.
Drive integrations with partner exchanges & custodians – ensuring frictionless implementation and ongoing performance.
Work cross-functionally with engineering, commercial, and marketing teams to prioritize features and ship products against tight deadlines.
Improve documentation, client journeys & onboarding experience for B2B partners.
Identify and solve critical product challenges – proactively pushing initiatives forward despite resource constraints.
Roll up your sleeves where needed – whether it’s product marketing, basic UX improvements, or technical documentation.

What Success Looks Like

Increased API adoption and partner satisfaction.
Faster, more reliable client integrations.
Demonstrable improvements in product performance and delivery speed.
Roadmap clarity and a structured product development process.

What We’re Looking For

2- 4 years of product management experience in a crypto native company.
Proven track record of shipping products in crypto, ideally in yield, staking, custody, or B2B2C API-based products.
Strong problem-solving track record – e.g., solving major implementation or adoption challenges.
Comfortable working with engineering teams; understands API-based product design
Dynamic, outcome-driven personality – someone who gets things done and can influence stakeholders to move fast.
Hands-on attitude – willing to dive into product marketing, UX basics, and documentation when needed.
Crypto-native mindset – strong understanding of crypto users, exchanges, and ecosystem players.

Why Join Tesseract?

Be part of a fast-growing, institutional-grade crypto yield generation platform with global partners.
Direct impact on business success; this is a critical, high-visibility hire, not a back-office role.
Mentorship & rapid growth; work directly with the CEO and founder, with a clear path to Head of Product within 18 months.
Proven resilience & ambition; Tesseract Investment is a profitable, regulated crypto firm (supervised by the Finnish FSA) that has thrived through both bull and bear markets.
Shape the future of crypto yield products; join the core team driving Tesseract’s next growth phase, expanding its customer base and delivering innovative products to top-tier partners.

This is a rare opportunity to make a significant impact at one of the most well-established names in crypto yield.
